A wearable dehydration detector

Even professional athletes are terrible at staying hydrated. So BSX created the wrist-worn LVL, the first wearable to measure hydration in real time. Other wearables make surface measurements close to the skin, but LVL uses near-infrared light to peer beneath it and record changes in blood color, which are indicative of hydration levels. If the wearer is dehydrated, it alerts them with an on-screen message. Drink up! $199
